hich characteristic is constant for the car as it travels around the roundabout pictured below? (1 point) Responses Position Position Direction Direction Speed Speed Velocity Velocity
The characteristic that is constant for the car as it travels around the roundabout is Direction. The car always moves in a circular direction around the roundabout.
On a position-time graph, which of the following does the value of the slope indicate about the object?(1 point) Responses Velocity Velocity Total distance Change in position Change in position Change in direction
The value of the slope on a position-time graph indicates the object's Velocity.
The characteristic that remains constant for the car as it travels around the roundabout is its velocity.
To determine the characteristic that remains constant for the car as it travels around the roundabout, let's analyze each option:
1. Position: As the car moves along the roundabout, its position changes continuously as it goes from one point on the roundabout to another.
2. Direction: The car's direction does change while navigating around the roundabout. Initially, the car is heading in a specific direction, but as it follows the circular path, its direction updates continuously.
3. Speed: Since the car travels around the roundabout, its speed may fluctuate depending on various factors such as the curvature of the roundabout, the driver's actions, or other external variables. Therefore, the speed is not a constant characteristic.
4. Velocity: Velocity is a vector quantity that takes into account both speed and direction. As discussed earlier, the car's direction changes while it moves around the roundabout. Hence, the velocity is not constant either.
Based on the analysis above, the only characteristic that remains constant for the car as it travels around the roundabout is its position. Therefore, the correct answer would be "Position."
